You can copy the code used in these examples in one of two ways. First, you can mouse over any code chunk and click the clipboard icon, , that appears.
Second, you can scroll to the top of your screen. You will see “</> Code” written in gray in the right corner. If you click that, you will get a little menu that allows you to hide or show all the code chunks on an example page, and also copy the code for the entire page.
